FIELD OF THE INVENTION

This invention relates to agricultural pesticide compositions and, in particular, to agricultural pesticide compositions containing deposition control agents.

BACKGROUND OF THE INVENTION

Many agricultural pesticides, including insecticides, fungicides, herbicides, miticides, and plant growth regulators, are applied in the form of a liquid composition. In addition to the pesticide, such liquid compositions typically include one or more adjuvant compounds intended to improve one or more properties of the liquid composition, such as for example, storage stability, ease of handling, deposition of the active ingredient on the target and/or pesticide efficacy against target organisms.

SUMMARY OF THE INVENTION

In order to improve the deposition of the active ingredient on the target, and thereby in order to improve the efficacy of the spraying, the use of deposition control agents is known. Deposition control agents include drift control agents, anti-bouncing agents, anti-splashing agents, anti-leaching agents, anti-misting agents, anti-roll off agents, and combinations thereof.

Drift control agents are additives that, typically through control of droplet size, render spray droplets less susceptible to being blown off-target and missing a target area. Anti-bouncing agents (also known as anti-rebound agents) are additives that render the spray droplets less susceptible to bouncing, rebounding, or splashing when the droplet hits a target surface, for example a leaf, and thus reducing loss of active ingredient to the ground, Anti-leaching agents (also known as rain-fastness agents) are additives that, after deposition of droplets onto a target surface, render the spray droplets less susceptible to removal from the target surface by rain or wind and/or allowing a long lasting effect of the active. In each case, the deposition control agent improves efficiency and permits a reduction of the amount of active ingredient used, which in turn reduces economic and environmental concerns. Anti-roll off agents, also known as sticking agents, are additives that render spray droplets less susceptible to rolling off or falling off the target surface.

There is a continuing interest in developing adjuvants for improved deposition control, e.g., controlling drift of spray applied pesticides or controlling rebound or roll-off of spray applied pesticides, that exhibit high performance when present in a spray composition in low amount and that are relatively insensitive to the amount of adjuvant in the spray composition.

In a first aspect, the present invention is directed to an adjuvant composition for modifying the spray properties of an aqueous pesticide composition, comprising:

-   (a) at least one fatty deposition control agent, and -   (b)(i) a liquid medium, one or more hydrotropes, and, optionally one     or more surfactants, or -   (b)(ii) one or more surfactants, optionally, one or more hydrotropes     or a liquid medium.

The adjuvant composition is capable of forming a stable emulsion upon dilution into an aqueous solution. The adjuvant composition, in one embodiment, comprises at least one fatty deposition control agent and at least one surfactant. The surfactant can be any suitable surfactant, which includes but is not limited to polyalkoxylated triglycerides, fatty acid glycol ester surfactants, or a combination thereof. The fatty deposition control agent can, in another embodiment, comprise one or more fatty alkanes, fatty amines, fatty acids, fatty amides, fatty glycerides, fatty triglycerides, fatty acid esters, or a mixture thereof. The fatty deposition control agent can, in another embodiment, comprise one or more fatty alkanes, fatty amines, fatty acids, fatty glycerides, or mixtures thereof

In one particular embodiment, the adjuvant composition comprises: (a) at least one fatty deposition control agent that comprises one or more fatty acids, and (b)(ii) at least one surfactant. The fatty acid can comprises oleic acid, linoleic acid, tall oil fatty acid or mixtures thereof.

In another embodiment, the adjuvant composition comprises (a) at least one fatty deposition control agent comprises one or more fatty acids, and (b)(ii) the at least one surfactant comprises a polyalkoxylated triglyceride.

In another embodiment, the adjuvant composition comprises: (a) at least one fatty deposition control agent that comprises one or more fatty triglycerides, and (b)(ii) at least one surfactant that comprises polyalkoxylated triglycerides, fatty acid glycol ester surfactants, or a combination thereof. In one embodiment, the one or more fatty triglycerides is present in an amount ranging from 70% to 99% by weight of composition. In another one embodiment, the one or more fatty triglycerides is present in an amount ranging from 60% to 90% by weight of composition, or in another embodiment present in an amount ranging from 65% to 98% by weight of composition, or in another embodiment present in an amount ranging from 65% to 80% by weight of composition.

In one embodiment, the adjuvant composition comprises: (a) at least one fatty deposition control agent comprising one or more fatty acid esters and (b)(ii) one or more surfactants selected from alkoxylated alcohol surfactants. In one particular embodiment, the fatty acid ester is a methyl ester of lauric acid.

In one embodiment, the concentrated pesticide composition is a homogenous liquid. In another embodiment, the concentrated pesticide composition forms a stable emulsion upon dilution with water. Generally, problems arise if the concentrated pesticide composition does not form a stable emulsion or maintain homogeneity when diluted in water (typically the spray solution). For example, the spray solution or diluted pesticide concentrate, if unable to form a stable emulsion or maintain homogeneity, becomes unusable and cannot be spray applied (e.g., clogs up the lines from the spray tank to the nozzle, clogs up the nozzle).

Optionally, the concentrated pesticide composition includes at least one surfactant. In one embodiment, the fatty deposition control agent is a fatty drift control agent and/or a fatty anti-rebound agent and/or a fatty anti-roll off agent.

In one embodiment, where the fatty deposition control agent is a fatty acid, the concentrated pesticide composition is free of surfactant. In one embodiment, “free of surfactant” means completely free or substantially free of surfactant, i.e., where there may be trace amounts of surfactant present.

In another aspect, the present invention is directed to an end use pesticide composition, comprising:

-   -   water,     -   one or more pesticide compounds, and     -   at least one fatty deposition control agent, in an amount         effective as a deposition control agent.

In one embodiment, the end use pesticide composition includes at least one surfactant. In another embodiment, the at least one fatty deposition control agent is one or more fatty acids.

The one or more fatty triglycerides or one or more fatty acids can be present in an amount ranging from 0.001% to 5% by weight of composition, or in other embodiments present in an amount ranging from 0.01% to 4% by weight of composition, or present in an amount ranging from 0.01% to 3% by weight of composition, or present in an amount ranging from 0.01% to 2% by weight of composition. In one embodiment, the one or more fatty triglycerides or one or more fatty acids can be present in an amount ranging from 0.01% to 1% by weight of composition.

In one embodiment the fatty deposition control agent is a fatty drift control agent. In another embodiment, the fatty deposition control agent is a fatty anti-rebound agent. In another embodiment, the fatty deposition control agent is a fatty anti-roll off agent.

In a further aspect, the present invention is directed to a method for controlling deposition of an aqueous pesticide composition that comprises one or more pesticide compounds and water, said method comprising: incorporating in the aqueous pesticide composition, in an amount effective as a deposition control agent, at least one fatty deposition control agent, and spray applying the aqueous pesticide composition and deposition control agent to a target pest and/or to the environment of the target pest, wherein the spray applied aqueous pesticide composition exhibits improved deposition control compared to an analogous spray applied aqueous pesticide composition that lacks the at least one fatty deposition control agent.

-   -   (a) at least one fatty deposition control agent, and     -   (b)(ii) a liquid medium, one or more hydrotropes, and,         optionally one or more surfactants, or     -   (b)(ii) one or more surfactants, optionally, one or more         hydrotropes or a liquid medium,

and wherein the adjuvant composition forms a stable emulsion upon dilution into the pesticide composition; and

spray applying the aqueous pesticide composition and adjuvant composition to a target pest and/or to the environment of the target pest,

wherein the spray applied aqueous pesticide composition exhibits improved deposition control compared to an analogous spray applied aqueous pesticide composition that lacks the adjuvant composition.

In one embodiment, the adjuvant composition comprises at least one fatty deposition control agent and at least one surfactant. In another embodiment, the fatty deposition control agent can comprise one or more fatty acids. When the fatty deposition control agent is a fatty acid, in one embodiment, the fatty acid comprises oleic acid, linoleic acid, tall oil fatty acid or mixtures thereof.

In another aspect, described herein are methods for improving deposition control of an aqueous pesticide composition during a spray application, comprising:

contacting a concentrated pesticide composition with an aqueous spray solution, wherein the concentrated pesticide composition forms a stable emulsion upon dilution with water,

wherein the concentrated pesticide composition comprises:

an aqueous liquid medium,

one or more pesticide compounds, and

at least one fatty deposition control agent in an amount that is effective, when the concentrated pesticide composition is diluted and spray applied, to provide improved deposition control compared to an analogous diluted and spray applied pesticide composition that lacks the at least one fatty deposition control agent; and

spray applying the aqueous pesticide composition to a target pest and/or to the environment of the target pest.

In one embodiment, the spray applied aqueous pesticide composition exhibits improved drift control properties compared to an analogous spray applied aqueous pesticide composition that lacks the at least one fatty deposition control agent.

A spray applied aqueous pesticide composition that comprises an effective amount of the fatty deposition control agent as described herein exhibits improved deposition control (e.g, improved drift control or improved anti-rebound).

Where the fatty deposition control agent is a fatty drift control agent, the spray applied aqueous pesticide composition typically exhibits a smaller amount of small size droplets that are very susceptible to spray drift, for example, droplets of less than about 150 microns (“μm”) in size, compared to an analogous spray applied aqueous pesticide composition that lacks the at least one fatty drift control agent. This improvement typically results in a spray droplet distribution that is more focused within the desirable range of from 150 microns (“μm”) to 500 μm in size. The drift control performance of the composition comprising the fatty drift control agent is less sensitive to concentration than a high molecular weight polymeric drift control agent and has a less dramatic effect on the viscosity of the pesticide composition than a high molecular weight polymeric drift control agent.

In another aspect, the present invention is directed to a concentrated pesticide composition, comprising:

a liquid medium,

one or more pesticide compounds, and

at least one fatty deposition control agent, in an amount that is effective when the concentrated pesticide composition is diluted and spray applied, to provide improved deposition control properties compared to an analogous diluted and spray applied pesticide composition that lacks the at least one fatty deposition control agent. In one embodiment, the fatty deposition control agent is a fatty drift control agent and/or a fatty anti-rebound agent and/or a fatty anti-roll off agent. The compositions or methods described herein can optionally comprise at least one surfactant.

The aqueous spray composition of Example 12 was prepared by mixing Composition A at 0.5 wt % in water. The composition of Comparative Example C12 was water only. The aqueous spray compositions of Example 12 and Comparative Example C12 were each tested and recorded using high speed videography (Phantom V211 camera to capture videos at 3000 frames per second). A single drop of diameter 2-2.5 mm was produced from a precision needle and allowed to fall on an inclined 45 degrees hydrophobic substrate (parafilm) 5 ft below the tip of the needle. It was generally observed that when the drop impacted the surface it spread across to reach its maximum diameter then recoiled under the action of surface tension, and either remained on the surface or rebounded off the surface and/or rolled down the substrate surface. It was observed that the droplet of Comparative Example C12 retracted/rebounded and eventually rolled off the parafilm substrate. Under a similar time-frame, it was observed that the droplet of Composition A exhibited limited rebound. It was also observed that Composition A did not roll off similar to Comparative Example C12.

A single drop of diameter 2-2.5 mm was produced from a precision needle and allowed to fall on an inclined 45 degrees hydrophobic substrate (parafilm) 5 ft below the tip of the needle. It was generally observed that when the drop impacted the surface it spread across to reach its maximum diameter then recoiled under the action of surface tension, and either remained on the surface or rebounded off the surface and/or rolled down the substrate surface.
